How to configure HSRP on Cisco – Basic to Advanced

HSRP (Hot Standby Router Protocol) is one of the most popular First Hop Redundancy Protocols (FHRP) made by Cisco. It is Cisco proprietary protocol. The FHRP allows a router on a LAN segment to automatically take over if other fails. Today, in this lesson, we will learn to configure HSRP on Cisco IOS.

We will be following below network topology to implement our HSRP.

Basic HSRP configuration:

First of all, let’s configure IP addresses on WAN interfaces. In this case, interface gigabitEthernet 0/0 is the WAN interface for both of the routers.

Load-Balancing with HSRP:

To do the load balancing, we need to configure two HSRP groups (number of groups equals the number of routers). Here, for group 1, RTR-01 is active due to higher priority. And, for group 2, RTR-02 is the active, which has the higher priority.
